Wait, is it really possible for the SDP to be shut down? That’s surprising!

I disagree, it's gotta be D, 10.10.10.1 hasn't sent anything.

C seems unlikely, MTU issues are rare in this case.

Definitely B, R4 hasn't sent a label yet.

I think it's option A, the SDP is probably down.

I’m leaning towards option D because it makes sense that if 10.10.10.1 hasn’t sent a label, then R4 wouldn’t have one to show.

I feel like I’ve seen a question similar to this where the MTU settings caused issues, so option C might be worth considering.

I think option B could be right too, but I’m not entirely sure if the label exchange happens immediately or if there’s a delay.

I remember studying about SDP states, so option A seems plausible if the SDP is indeed down.

Wait, I'm a bit confused. Doesn't the "!-" operator mean "not equal to"? If that's the case, then wouldn't it allow null values to pass through?

The question mentions that some of the articles are more than 2 years old, so I'm leaning towards option D to focus on the top performing articles and avoid importing outdated content.

I keep getting confused about the purpose of financial controls. D sounds right for error and fraud prevention, but I'm not entirely sure!

I'm a bit confused about the label permissions. I think C makes sense, but I'm not sure if it's the one that's "not proper."

Hmm, I'm a bit confused by the wording here. Does "could" mean that it's optional to have separate specifications, or that it's a requirement? I'll need to think this through carefully before selecting an answer.
